For anyone interested in practising your Kelly estimation, I made a game inspired by Bernoulli's original paper on the subject for a lunch and learn at my job: https://static.loop54.com/ship-investor.html

There's also a sequel for the case of continuous outcomes: https://static.loop54.com/ship-investor-2.html

Before my parental leave is over, I hope to make two more sequels, one with futures and one with options. Maybe also a fixed-income version, but I'd have to learn more about that myself first.
